Connectors for stranded wire + PC mount screw terminals

I don't think the last poster has the whole thread in mind or perhaps he disagree's with my statement... as follows and quoted from my last post:

Soldering or "Tinning" the wire ends is ok IF you have a situation where the wires don't move (Wire clamps) but effectively makes solid wire and worse IF you have "Nicked" a wire or two in stripping the wire you have started the breaking process

.

Which part of what I said do you disagree with? I'm curious.
